A Review on Experimental Study of Heat Transfer from Plate Fin in Mixed Convection Mode

Pravin Kamble, S.N Doijode, Geeta Lathkar

Abstract: The work summarized in this paper presents an experimental study of heat transfer from plate fin in mixed convection mode enhancement by the use of pin fins is presented. After a brief review of the basic methods used to enhance the heat transfer by simultaneous increase of heat transfer surface area as well as the heat transfer coefficient, a simple experimental method to assess the heat transfer enhancement is presented. The method is demonstrated on plate fins as elements for the heat transfer enhancement, but it can in principle be applied also to other fin forms. That is varying various parameters (height, spacing). The order of the magnitude of heat transfer enhancement obtained experimentally, it was found that by a direct comparison of Nu and Re no conclusion regarding the relative performances could be made. This is because the dimensionless variables are introduced for the scaling of heat transfer and pressure drop results from laboratory to large scale but not for the performance comparison. Therefore a literature survey of the performance comparison methods used in the past was also performed. Experiments will carried out on mixed convection heat transfer from plate fin heat sinks subject to the influence of its geometry and heat flux. A total of 40 fins were bolted into the upper surface of the base plate. The area of the base plate is 120mm by 120mm. The base plate and the fins were made of aluminum. For all tested plate fin heat sinks, however, the heat transfer performance for heat sinks with plate fins was better than that of solid pins.
